Abstract

L'invention concerne un module de prélèvement de liquide (1) pour prélever du liquide dans un réservoir de liquide (18), en particulier d'un système de post-traitement de gaz d'échappement d'un véhicule automobile, comprenant un corps de base (2) qui peut être disposé dans et/ou sur le réservoir de liquide (18), présente un dispositif de prélèvement de liquide (36) pourvu d'au moins une ouverture de prélèvement (7) pouvant être associée à l'espace intérieur de réservoir (27) et porte au moins un élément filtrant (9) associé à l'ouverture de prélèvement (7). Selon l'invention, l'élément filtrant (9) au moins élastiquement déformable par endroits est disposé/conçu de manière qu'il présente une courbure (17) dirigée dans le sens opposé au sens d'écoulement de prélèvement (26). L'invention concerne également un réservoir de liquide (18) pour un véhicule, en particulier pour un système de post-traitement de gaz d'échappement d'un véhicule automobile.
